Embodiments include an inflatable support structure enclosing a region fillable by a fluid at a positive pressure above an atmospheric pressure. A flexible screen is attached to the support structure, a region between the flexible screen and the support structure fillable by a fluid at a negative pressure below the atmospheric pressure that holds the flexible screen in a shape suitable for image projection. A method according to embodiments includes inflating an inflatable support structure with a fluid at a positive pressure above an atmospheric pressure and removing fluid from a region between the support structure and a flexible screen attached to the support structure to hold the flexible screen in a shape suitable for image projection with the fluid at the negative pressure below the atmospheric pressure between the flexible screen and the support structure.

Dual pressure inflatable structure and method

Embodiments include a light engine to generate pixels and a number of lenses positioned to receive pixels from the light engine and to project the pixels on to a field with a higher angular pixel density at an edge of the field than at a center of the field. A method according to embodiments includes generating pixels in a light engine, receiving the pixels from the light engine in a plurality of lenses, and projecting the pixels through the plurality of lenses on to a field with a higher angular pixel density at an edge of the field than at a center of the field.

Optical projection system and method of use

An optical projection system includes an image source that is configured to generate an array of image pixels. A lens assembly is configured to project the array of image pixels onto a hemispherical surface at a projection angle greater than 180&#xb0;. The lens assembly may include a wide-angle lens assembly and an image relay lens assembly that is configured to reduce dispersion in the array of image pixels between the image source and the wide-angle lens assembly. The wide-angle lens assembly may include a meniscus lens assembly and a wavefront shaping lens assembly. The lens assembly may be further configured to project the array of image pixels onto the hemispherical surface such that there is a constant angular separation between adjacent image pixels. An optical projection system may also include two image sources that are configured to generate first and second arrays of image pixels and two lens assemblies that are configured to respectively project the first and second arrays of image pixels at projection angles that are greater than 180&#xb0; onto a surface in opposite directions of each other. The combination of the first and second arrays of image pixels may cover a continuous, 360&#xb0; portion of the hemispherical surface.
